This Sony Vertical Battery Grip for Alpha SLT-A77 Camera will
give you a firm hold on your camera, reducing the strain on your wrists
when you have long sessions shooting vertical photos. The shutter
button is right at your fingertip, and controls are conveniently
positioned for comfortable shooting. Made to be used with your Sony α77
DSLR camera, this vertical grip features a rugged design, gasket-sealed
buttons to protect against dust and moisture, and a built-in compartment
for two NP-FM500H InfoLITHIUM batteries (sold separately) for up to
1,060 shots. Plus, this grip automatically switches to backup battery
power for uninterrupted shooting.

Comfortable and Ergonomic

A firm, comfortable grip for vertical-position shooting with the
Sony SLT-A77. Buttons and controls are conveniently placed and easy to
reach for greater comfort.

Dual Batteries

Holds two InfoLITHIUM batteries for extended shooting (sold
separately). Stamina power for up to 1,060 shots. The battery grip does
not have a charging function, so the batteries would have to be charged
using the camera body.

Gasket-Sealed

The rugged, but lightweight, body design has gasket-sealed
controls to resist dust and moisture. The grip has a 1/4" tripod mount
on the bottom.

Auto Switching Power

When using two batteries, the grip will automatically switch to
the second battery if the first becomes depleted. Switching does not
interrupt camera operation.

Accurate Battery Life Indicator

Accurate remaining power indicator shows remaining power in
percentage. When using two batteries, indicators show which battery is
being used and what percentage of life is left.
